Adler has been credited with fostering Spielberg's interest in filmmaking. The Cincinnati native was a fan of the arts, as she herself studied at a music conservatory after learning to play piano at age 5. She most recently owned a kosher Los Angeles restaurant called the Milky Way.
In 1945, she married Arnold Meyer Spielberg and the couple went on to have four children together -- Steven, Anne, Sue and Nancy. Adler and Arnold later divorced in 1966. Her second husband, Bernie Adler, whom she wed in 1967, died in 1995 at 75. Arnold celebrated his 100th birthday this month.
In a statement to THR, Steven's production company, Amblin, said that "while known for her red lipstick and Peter Pan collars, for her love of daisies, for her blue jeans and sparkly bling, for her dancing from table to table around the Milky Way, and for her love of camping, fishing and crossword puzzles, Leah is best remembered for her deep, limitless love for the people around her."
Adler's survivors include Steven and daughters Anne, Sue and Nancy, as well as 11 grandchildren and five great-grandchildren.
